I improved the $noiseArray to this:
$noiseArray = array("[:alnum:]", "[:punct:]", "|", "\\", "<", ">","#", "@", "\$", "%", "^", "&", "*", "(", ")", "-", "_", "+", "=","[", "]", "{", "}", "about", "after", "all", "also", "an", "and","another", "any", "are", "as", "at", "be", "because", "been","before", "being", "between", "both", "but", "by", "came", "can","come", "could", "did", "do", "does", "each", "else", "for", "from","get", "got", "has", "had", "he", "have", "her", "here", "him","himself", "his", "how", "if", "in", "into", "is", "it", "its","just", "like", "make", "many", "me", "might", "more", "most", "much","must", "my", "never", "now", "of", "on", "only", "or", "other","our", "out", "over", "re", "said", "same", "see", "should", "since","so", "some", "still", "such", "take", "than", "that", "the", "their","them", "then", "there", "these", "they", "this", "those", "through","to", "too", "under", "up", "use", "very", "want", "was", "way", "we","well", "were", "what", "when", "where", "which", "while", "who","will", "with", "would", "you", "your");
Do any of the characters in there need escaping (other than the $which is already escaped)?
How does on go about looping through the array, matching only wholewords? This didn't quite do it:$searchQuery=str_replace( "^".$noiseArray."$", " ", $searchQuery);
And neither did this:$searchQuery=str_replace( "/^".$noiseArray."$/", " ", $searchQuery);
Thanks.
